Stan - I bookmarked your page to peruse at a later date. Kate and Stella are lovely girls, similar to my two. My mother was born in Whangarei (sp?) so we have more than chestnuts in common.
How Clever - Why would I need an excuse?

Sienna looks great in her woolly winter coat.
Just to be clear about her feeding program. Sienna receives routine groceries (freechoice pasture, water, hay, salt mineral licks). Serious groceries (lucerne stud mix) x 2 day. Frivoulos groceries (chopped fruit/veg/garlic/ACV in oats) once a day and Treats (popcorn and dates) often enough that she catches herself.
Bubba13 - Thanks for your concern. She is 2.5 years into recovery from starvation and neglect. Apart from having no molars and a clicky stifle she is as healthy as a horse. LOL She has a whole new lease on life since Piper joined us.
Everyone - so is the lighter (brassy) chestnut what is called sorrel in the US?
